What are static friction, sliding friction and rolling friction, and what are the differences? For example, (Third Grade Physics)

Static friction exists between two objects that have a tendency to move with each other but do not move with each other, such as a wooden block resting on an inclined plane. There is static friction between the wooden block and the inclined plane to ensure that the wooden block will not move. decline. Sliding friction exists between two objects that move with each other, such as a wooden block sliding on a flat surface. There is sliding friction between it and the flat surface. Rolling friction is the sliding friction when sliding turns into rolling. For example, when a car is driving on the road, the wheels are rolling, so the friction between the wheels and the road is rolling friction.

For the same pair of contact surfaces, static friction is variable, while sliding and rolling friction are fixed
